<td>smfi_replacebody fails and returns MI_FAILURE if:

<li>bodyp == NULL and bodylen > 0.
<li>Changing the body in the current connection state is invalid.
<li>A network error occurs.
<li>SMFIF_CHGBODY was not set when <a href="smfi_register.html">smfi_register</a> was called.
</ul>
Otherwise, it will return MI_SUCCESS.

<!----------- Notes ---------->
<tr align="left" valign=top>
<th>NOTES</th>
<td>
<ul>
<li>Since the message body may be very large, setting SMFIF_CHGBODY may significantly affect filter performance.
<li>If a filter sets SMFIF_CHGBODY but does not call smfi_replacebody, the original body remains unchanged.
<li>For smfi_replacebody, filter order is important. <b>Later filters will see the new body contents created by earlier ones.</b>
</ul>
